The general public are going to get sucked into whatever the headlines tell them to buy.
Also as you allude to, most people just want to get-rich-quick and aren't interested in a new payments system,
And that's most likely what's driving the crypto bubble - common folks searching for a profitable place to invest their savings.
I believe what gives Bitcoin value is the promise of usability as a means of payment. It is not and cannot be a safe "store of value" without a good usability value - if the only usability case is speculation on future bitcoin prices (plus some criminal corner-cases, including tax evasion), then Bitcoin is just an advanced ponzi scheme, it's bound to crash hard at some point.
I have some digital tulips for sale! Do you want to buy some?
